FIELD OF THE INVENTION

The present invention is related to computer software and morespecifically to computer software for customizing web pages.

BACKGROUND OF THE INVENTION

Web pages contain text and links inserted by the author of the web page.However, the links are not customized for each user who views the webpage, making them less personalized for that user. What is needed is asystem and method that can provide links that are customized for eachuser that can be of additional interest to each particular user of a webpage.

SUMMARY OF INVENTION

A system and method uploads from a client to a server the URLs of webpages being visited by a user. For each URL received, the serverretrieves the web page and for each page, identifies other web pagescorresponding to terms used on the web page being viewed by the user,and provides URLs to the other web pages for such terms to the client.The client inserts links to such other pages in the web page beingviewed by the user and causes terms on the web page with which the usercan interact to reach such other web pages to be displayed in a formatdifferent from that used by the author of the page, either as a resultof the link insertion or using other techniques.

The other web pages that are of interest to a user may be selected fromamong a set of web pages that correspond to the terms on the web pagebeing viewed by the user.

The other web pages are selected in part based on how interesting to theuser the term to which the web page corresponds is predicted to be,based on the user's experience with such terms and other user's actionsregarding such terms, where the other users may be those that aresimilar to the user.

The other web pages are also selected in part based on how relevant theother page is to the web page being viewed by the user, and for otherqualities of the other pages.

The other web pages are also selected in part based on the degree towhich the user is predicted to find the web page of interest, based notonly on information known about the user, but also the actions of otherusers, such as those at least similar to the user viewing the web page.

The terms that get selected to be linked may be constrained, forexample, ensuring that they are limited in number and spread throughoutthe page and not too close to one another, and the pages that getselected may also be constrained, for example, by limiting them to amaximum number and also limiting maximum numbers of types of pages.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

1. Conventional Computer Systems.

The present invention may be implemented as computer 20 software on aconventional computer system. Referring now to FIG. 1, a conventionalcomputer system 150 for practicing the present invention is shown.Processor 160 retrieves and executes software instructions stored instorage 162 such as memory, which may be Random Access Memory (RAM) andmay control other components to perform the present invention. Storage162 may be used to store program instructions or data or both. Storage164, such as a computer disk drive or other nonvolatile storage, mayprovide storage of data or program instructions. In one embodiment,storage 164 provides longer term storage of instructions and data, withstorage 162 providing storage for data or instructions that may only berequired for a shorter time than that of storage 164. Input device 166such as a computer keyboard or mouse or both allows user input to thesystem 150. Output 168, such as a display or printer, allows the systemto provide information such as instructions, data or other informationto the user of the system 150. Storage input device 170 such as aconventional floppy disk drive or CD-ROM drive accepts via input 172computer program products 174 such as a conventional floppy disk orCD-ROM or other nonvolatile storage media that may be used to transportcomputer instructions or data to the system 150. Computer programproduct 174 has encoded thereon computer readable program code devices176, such as magnetic charges in the case of a floppy disk or opticalencodings in the case of a CD-ROM which are encoded as programinstructions, data or both to configure the computer system 150 tooperate as described below.

In one embodiment, each computer system 150 is a conventional SUNMICROSYSTEMS SPARC ENTERPRISE M9000 SERVER running the SOLARIS operatingsystem commercially available from ORACLE CORPORATION of Redwood Shores,Calif., a PENTIUM-compatible personal computer system such as areavailable from DELL COMPUTER CORPORATION of Round Rock, Tex. running aversion of the WINDOWS operating system (such as 95, 98, Me, XP, NT,2000, 7 or VISTA) commercially available from MICROSOFT Corporation ofRedmond Wash. or a Macintosh computer system running the MACOS orOPENSTEP operating system commercially available from APPLE INCORPORATEDof Cupertino, Calif. and the FIREFOX browser commercially available fromMOZILLA FOUNDATION of Mountain View, Calif., the CHROME browsercommercially available from Google, Inc. of Mountain View, Calif. orINTERNET EXPLORER browser commercially available from MICROSOFT above,although other systems may be used. Each computer system 150 may be aDROID 2 mobile telephone commercially available from MOTOROLACORPORATION of Schaumberg, Ill. running the ANDROID operating systemcommercially available from GOOGLE, INC. of Mountain View, Calif. or aniPhone commercially available from APPLE, INC of Cupertino, Calif.,though other systems may be used. Various computer systems may beemployed, with the various computer systems communicating with oneanother via the Internet, a conventional cellular telephone network, anEthernet network, or all of these.

2. Display of Additional Information to a Web Page.

Referring now to FIG. 2, a method of adding links to web pages is shownaccording to one embodiment of the present invention. A user mayoptionally register 210 to a server (or at a later time to a programrunning on the user's computer system, with the registration informationuploaded by that program to the server), for example by providinginformation about the user and that user's interests and preferences.The server is coupled to the user's client computer system via a networksuch as the Internet. Information about the user may include demographicinformation such as age, and sex, zip code, and other similarinformation. Such information about the user may include any informationthat allows other users who have similar characteristics (e.g. otherusers in the same age range as the user) to be associated with thatuser. Interest and preference information may include information aboutthe user's interests, such as by selecting five interests from among 25possible interests, with the user's preferences being implied to bethose the user has selected being preferred over those the user has notselected. Among the interests the user selects, the user may rank theinterests, which defines the user's preference of such ranked interestsrelative to one another. Other conventional interest and preferenceinformation may be received from the user.

A browser add on or application add on or enhancement that operates asdescribed below may be optionally provided and installed 212, forexample, in the user's browser. The techniques described herein may beused without a browser or application or the techniques may beincorporated into the operation of the browser itself, withoutseparately adding such functionality into a browser as an add on,extension, browser application, etc.

One or more requests may be optionally provided 214 to receivenotification of a new web page being loaded by a browser or application,for example, or the user clicking on a new tab or the browser orapplication losing focus. In one embodiment, such request is inherent instep 212, and in another embodiment, the request is made explicitly, forexample, to a browser, application or operating system. In still anotherembodiment, such as when the method of the present invention is builtinto a browser, no explicit request is made, but the browser willprovide such information to the system and method of the presentinvention as part of its operation. In one embodiment, a user specifieseach web page requested to the system and method and so no notificationis required.

In one embodiment, some of the steps of the method of the presentinvention may be performed on a server, coupled to multiple clientcomputer systems via the Internet. The client computer systems receiveinformation from the user and the browser or application and upload itto the server. For each client computer system, the server processes theinformation and instructs the client computer system how to modify theweb page as described herein and the client computer system so modifiesthe web page. In such embodiment, the client requests from the server aunique user identifier and stores it to be sent with all subsequentcommunications to the server and the server issues a unique useridentifier to the client, which the server and client each store 216.

In one embodiment, step 216 includes uploading history information forthat user. History information may include pages the user has visitedand searches terms the user used when performing searches through asearch bar on the browser or other application or when using aconventional search page.

A notification of a new page is received 218, for example, from theuser's browser. The notification is provided when the user specifies anew web page to view, in the address bar, via a favorite link, or via alink or button on a web page previously displayed. The notification mayalso be provided when the user switches tabs to view a web page alreadyviewed or when the user changes focus to, or away from, an application,such as a browser, that is displaying a web page. The URL may be locallystored and is also uploaded to a server along with any search terms theuser used to reach the page, and the server retrieves the web pagecorresponding to the URL it received 220, as a browser would. In oneembodiment, the server may check a cache of web pages that it hasrecently retrieved for that user or another user and may use the webpage from the cache if the web page is within a threshold amount of timeor the date and time specified by an Expires header supplied with theweb page. If the page is in the cache and the current time is not pastthe threshold time or the Expires time, the page is retrieved from thecache instead of retrieving it from the source. The server analyzes 222the page to identify relevant terms on the page as described below withrespect to FIG. 3, and the server selects the most relevant terms andprovides them via a network such as the Internet to the 5 clientcomputer system. Because the same term may be on the web page severaltimes, in one embodiment, the server also provides an indication of theinstance of the term on the page, though in another embodiment, no suchinstance indication is provided and all instances may be used as portalsor links to additional information as described herein, or the clientmay select one at random or in a manner that spreads each instance asfar away from the other terms used as portals or links to additionalinformation as possible.

When it receives such information, the client causes the terms on theweb page to be portals or links to additional information as describedbelow. Terms that are portals or links to additional information may bedisplayed at the client computer system using different formatting fromthat used by the author of the page, either because they have beenconverted to links that the browser will display using differentformatting or otherwise. The client instruments the web page to causeinterest indications or clicks of the terms indicated as being portalsor links to additional information or other areas to be processed asdescribed below and the web page instrumented and indicated in thismanner is redisplayed (or the initial display may be delayed until theweb page is so instrumented and indicated, and is displayed with thereformatting and instrumentation) 224.

In one embodiment, the terms may be provided by the server to the clientwith an indication of the degree of relevance to the user of the termsand the client computer system will indicate the terms as being a portalor link to additional information differently, e.g. in different color,or with a different icon, or using other differences, according to theirdegree of relevance.

In one embodiment, a term may be indicated as being a portal or link toadditional information by underlining it, and in another embodiment, aterm may be indicated as being a portal or link to additionalinformation by shading the white space around it. In still anotherembodiment, a term may be indicated as being a portal or link toadditional information by displaying it in a different color. In oneembodiment, no change in appearance for a term indicated as being aportal or link to additional information occurs until the user doessomething like hover the mouse cursor over the term for at least aminimum period of time, like three quarters of a second, and in stillanother embodiment, a term indicated as being a portal or link toadditional information is displayed using another conventional method ofdisplaying information in a distinctive manner.

In one embodiment, the client computer system will not provide the URLof a page containing search results, as indicated by the URL, but willstrip the search terms from the URL parameter passing information in theURL and provide it to the server when the user clicks on one of thelinks in the search results page. If the client does not click on alink, the search term either may be provided to the server at a latertime, or not provided to the server. In another embodiment, as part ofstep 222, the server identifies whether the page contains a set ofsearch results based on the URL of the page and optionally the URLparameter passing information to the right of the base URL of the webpage. If the page contains a set of search results, the server storesthe search term as described above but otherwise does not perform step222 and step 224 is not performed.

At any time, the user may provide an interest indication, indicatinginterest in a term indicated as being a portal or link to additionalinformation for example, by hovering over or very near such a term forat least a minimum threshold amount of time (e.g. one half second or onesecond) and such interest indication is received at the client computersystem 226. When such an interest indication is received, the clientcomputer system requests from the server, information relevant to theterm corresponding to the interest indication, for example, by providingthe text of the term indicated as being a portal or link to additionalinformation and the user identifier, and such relevant information isprovided by the servers received by the client and displayed by theclient computer system 228.

In one embodiment, the relevant information is information thatdescribes in some way the information the user will see if the userclicks the term indicated as being a portal or link to additionalinformation. For example, the relevant information may includeinformation from the URL corresponding to a link that is activated whenthe user clicks the term indicated as being a portal or link toadditional information, and a title, image, icon or summary of theinformation contained in the web page corresponding to that link.

Some or all of the relevant information (i.e. the information relevantto the term indicated as being a portal or link to additionalinformation) may be displayed in any of a variety of ways. The relevantinformation may be displayed in a tool bar, as a small pop up windowjust above (or otherwise near) the term indicated as being a portal orlink to additional information and corresponding to the interestindication, or elsewhere. The relevant information may be displayed inthe status bar of a browser, or other similar component of a differentapplication. Other conventional means of displaying the relevantinformation may be used.

For example, a web page the user is viewing may be a web page discussingcurrent nominations for the GRAMMY AWARDS. One of the nominees may beBritney Spears, and such term may be indicated as being a portal or linkto additional information as described herein. If the user provides aninterest indication for that term, relevant information about a link tomore information about that term is displayed. For example, the relevantinformation may be the words: “en.wikipedia.org: Britney Spears”, where‘Wikipedia.en’ is a portion of the URL to the English language versionof Wikipedia.com, and Britney Spears is the title of the page the user'sbrowser will request if the user clicks on the term indicated as being aportal or link to additional information.

In one embodiment, the relevant information may include informationprovided by the author of the page to which the term is, or will be,linked. For example, the relevant information may include a message orset of phrases or both, each provided by or on behalf of the page towhich the term is or will be linked. In one embodiment, the display ofthe relevant information may be interactive and allow the user to choosefrom among multiple different sources of information that may be used asthe link described below. For example, if the user right clicks thedisplay of the relevant information, additional relevant information isdisplayed. The additional relevant information includes otherinformation corresponding to the term indicated as being a portal orlink to additional information, such information being retrieved fromthe server when the user right clicks the term indicated as being aportal or link to additional information. For example, the additionalrelevant information may be the following phrases, each corresponding toa different link: “Britney Spears Concert Tickets”, “Britney SpearsMusic”, “Britney Spears Photos”. Icons may be used instead of the wordsto indicate the type of information. A relevance score may be displayedwith each icon or phrase to indicate the degree of relevance of theinformation to the term the user will see if the user clicks the phraseor icon.

The user may select the phrase from the relevant information in whichthe user is interested and the link corresponding to the selectedrelevant information phrase will be used when the user clicks it asdescribed below. If the user does not select a different phrase, thefirst phrase or icon or a default phrase or icon is used for the link asdescribed below. This technique may be performed as part of step 228.

In one embodiment, the relevant information received from the serveralso contains at least one URL to a web page the user can view if theyclick on the term indicated as being a portal or link to additionalinformation or phrase or icon. In the embodiment in which the user mayselect a phrase of the relevant information, the relevant informationmay contain a URL for each such phrase or icon, or when a phrase or iconis selected, the client computer system provides the identifier assignedas described above and an indication of the phrase or icon selected andthe server provides the link that corresponds to that phrase or icon aspart of step 228.

At any time, the user may perform an action and an indication of theaction is received, and uploaded by the client to the server, along withthe user identifier and the server timestamps and stores suchinformation for use as described herein 230. The action may be to selecta new page, new tab or change the focus, and the browser or otherapplication so indicates and the indication is received, in which case232 the method continues at step 218. The action may be to provide aninterest indication which the browser or other application communicates,in which case 232 the method continues at step 228. The action may be toclick on a term indicated as being a portal or link to additionalinformation and the browser or other application receives the click andprovides an indication of the clicked term to the system and method ofthe present invention, in which case 232 the method continues at step234. The action may be to scroll up or down or page up or down, hoverover a link, move the mouse around the page, interact with a web form(e.g. making a selection, pushing a button, typing in the form, etc) oranother indication that the user is or is not reviewing or interactingor is otherwise engaging with the page being displayed, and the browseror other application communicates the action, in which case 232 themethod continues at step 230.

At step 232, the user's browser or other application is redirected tothe URL associated with the relevant information for the link and themethod continues at step 218.

As noted, in the case of each action, such action is recorded anduploaded by the client to the server with the user identifier issued asdescribed above and the server stores such information along with thedate and time of receipt. This allows the server to identify what a userdoes with each web page or other sets of information the user receives.The amount of time between actions can also provide an indicationregarding whether the user found the information useful or not.

3. Identifying the Terms to Indicate as being a Portal or Link toAdditional Information and the Web Pages to Link to the Terms.

Referring now to FIG. 3, consisting of FIGS. 3A and 3B, a method ofidentifying information to add to a web page is shown according to oneembodiment of the present invention.

A. Retrieve Web Page, Identify Terms, Intent.

A user identifier and URL of a web page is received, the page isretrieved and terms on the page are identified 310. For example, theevery combination of one, two, three, four, five or six consecutivewords not separated by certain punctuation (e.g. a comma, semicolon,period followed by two spaces, while allowing for the words “Dr. JimJones” to be a term) on the page and not part of a link or an HTML tagor attribute (e.g. in the tag “<strike>”, the word ‘strike’ is ignored)may be identified as a term on the page, though other types of terms maybe used. In one embodiment, terms may overlap. For example, in a groupof consecutive words, the first three and the last three words may betwo different terms, the first two words may correspond to a third term,and so on.

In one embodiment, an intent is identified from among several potentialintents as part of step 310. The intent may not be the actual intent ofthe user, but may indicate the intents of many users or most usersbrowsing that page. Intent indicates what the user might be trying to dowhen viewing a web page. For example, if the user is on a travel website that sells travel services on a page in which travel services maybe browsed or ordered, the intent of the user may be identified as being“purchase”. If the user is on a travel web site that providesinformation, the intent of the user may be “information gathering”.Other intents may be “entertainment”, “review of reference material” andso on. The intent of the user may be determined using the URL of thepage, and words on the page. The domain of the URL may be looked up in adatabase that may provide an indication of possible intents for pages inthe domain, and then the words of the page may be used to distinguishamong the possible intents if more than one exists.

For example, the domain expedia.com may have only one intent: purchase.A vacation web site that both provides information and allows a purchasemay have both “information gathering” and “purchase” intents, with thecontent of the page being used to discern from among the two intents. Apage in this web site that uses the words “add to cart” may indicatethat the intent is “purchase” for that page.

B. Assign Other Scores to the Terms on the Retrieved Page.

1. Score Based on the Relevance of the Terms to User's Prior Actions notDirectly Related to the Terms.

One or more scores may be identified for each term resulting actions theuser has taken that were not necessarily performed in the presence ofthe term. One such score is a term search relevance score.

A term search relevance score is identified 312 for each term identifiedas described above. The term search relevance score is higher if theterm contains words or synonyms of words from recent searches than it isif the term has no words or synonyms from recent searches performed bythe user. In one embodiment, the term search relevance score is higherif such correspondence with search terms is more recent than it is ifthe search terms to which the term corresponds were less recently usedby the user. In one embodiment, the term search relevance score ishigher if the term has a greater percentage of words that match orcorrespond (e.g. via a synonym table) to the recent search terms than itdoes if a lesser percentage of words of the term match or correspond torecent search terms. In one embodiment, the search term relevance scorehas a higher value if the term corresponds to many recent search termsthan it does if the term corresponds to few recent search terms. Theterm search relevance score is a score based on an action that the usertook that was not necessarily performed in the presence of the term,because it may be positively related to the term without the user beingin the presence of the term when the user thinks of the search to takethe action. The search term the user uses need not be displayed anywhereat the time the user thinks to use it. Such a score is referred to as a“sinepresence score” because neither the term nor an inventory page needbe visible to the user when the user decides to perform the action onwhich the score is evaluated.

At this point, in one embodiment, what is assigned to the retrieved pageis an intent, and a term search relevance score for each termidentified. This may be written in short hand as: Retrieved Page(intent); Each Term (term search score). It is noted that scores may beassigned in other orders than the order described here.

2. Score Based on the User's Prior Experience with Each Term.

For each term on the page, a score corresponding to the number of timessuch term has been seen on web pages whose URLs were uploaded by theclient corresponding to the user identifier received is identified and ascore corresponding to the number of times the term indicated as being aportal or link to additional information was displayed to the usercorresponding to the user identifier received from the client is alsoidentified 314. The “number of times the term was seen by the userscore” is higher if such term has been seen by that user fewer times andlower if such term has been seen by the user a higher number of times.The “number of times the term indicated as being a portal or link toadditional information was displayed to the user score” is higher ifsuch term has been seen by that user when it was displayed indicated asbeing a portal or link to additional information fewer times and lowerif such term has been seen by the user when it was indicated as being aportal or link to additional information a higher number of times.

In one embodiment, step 314 may also include identifying an “interestindication score” for each term. An interest indication score is higherif the user, when presented with the term indicated as being a portal orlink to additional information, provided an interest indication such ashovering above it for more than a threshold amount of time morefrequently and is lower if the user, when presented with the termindicated as being a portal or link to additional information, providedan interest indication such as hovering above it for more than athreshold amount if time less frequently.

Thus, in one embodiment, what is assigned to the retrieved page andterms are: Retrieved Page (intent); Each Term (term search score, numberof times the term was seen by the user score, interest indicationscore).

3. Score Based on Other User's Prior Actions with Respect to the Terms.

A similar other user click score is identified for each term on the page316. The similar other user click score measures the percentage of otherusers who are similar to the user corresponding to the user identifierreceived who, when the term was indicated as being a portal or link toadditional information, clicked on it causing a web page (which may notnecessarily be the selected web page) in the corresponding link to beviewed.

In one embodiment, a similar other user is a user who has similarpreferences to the user, similar demographics to the user or any or bothof these. In one embodiment, a similar other user is a user who hassimilar preferences and/or demographics to the user and/or has, within athreshold amount of time (e.g. 1 month), visited the web site containingthe page containing the selected term in a number of times that iswithin the same range as the user having the identifier received. Theranges may be under times in the last week, 6-20 times in the last week,or more than 20 times in the last week, for example. In one embodiment,a similar other user is a user who has similar preferences and ordemographics as described above, but clicks from users who have similarweb visit ranges as described above are weighted higher than clicks fromother users who don't when computing the score. If the user has notprovided preference or demographic information, web sites visit rangesmay be used instead to identify similar other users. A threshold matchmay be employed, for example, a user who has visited at least tenpercent of the same web sites as the user whose user identifier wasreceived may be considered a similar user. Thresholds may be determinedbased on other factors, such as the type of web sites in common.

In one embodiment, instead of or in addition to visiting the same websites, visits within the same range to the same type of web sites (e.g.financial web sites, sports web sites, etc.) as those visited by theuser may be used to identify similar other users. In one embodiment, adatabase that categorizes web sites according to a user's interests maybe used, for example identifying web sites as financial web sites, andother web sites as news web sites and still other sites as other typesof web sites.

In one embodiment, a similar other user is a user who not only visitsthe same web sites or types of web sites a similar number of times, butalso exhibits a similar level of engagement with the web site or withsome or all of those types of sites. Engagement may be measured by theactivities performed at the site, with filling out a form being thehighest level of engagement, scrolling up or down or paging up or downover a period of time such as a few minutes representing a medium levelof engagement, and not scrolling or paging up or down or doing soquickly representing the lowest level of engagement. Other indicationsof engagement may be used.

In one embodiment, the registration process includes receiving anidentifier of the user's account at a social network web site. In oneembodiment, a similar other user may be any user associated with theuser at the social network web site.

The user is the user corresponding to the user identifier received instep 310. It is noted that the user may not be identified to the levelof an individual with any certainty because the user's browser orapplication may be shared with other users. The “user” is thus any userwho provides the same user identifier to the server via a browser orother application.

Thus, in one embodiment, what is assigned to the retrieved page andterms are: Retrieved Page (intent); Each Term (term search score, numberof times the term was seen by the user score, interest indication score,similar other user click score).

C. Identify Inventory Pages Corresponding to Terms, Assign Term Scoresto Terms Corresponding to Each Inventory Page.

In one embodiment, a catalogue or an inventory of pages (sometimesreferred to as “inventory pages”) that may be linked from pages viewedby users may be maintained, with the contents of each page storedassociated with the URL to reach that page. In one embodiment, a messageor phrase or both may be maintained with some or all of the pages, to beused as some or all of the relevant information for the page. Themessage or phrase may be provided by a party from which the inventorypage was received, or on that party's behalf. It is noted that in oneembodiment, the available inventory of web pages is available for theserver to analyze, for example, using a conventional cache or by a bruteforce method of storing every such page. The pages in the inventory maybe updated from time to time, such as nightly, or at such time asindicated by the Expires header of the page.

Pages in inventory may be stored where they can be reached via theInternet. For example, inventory pages may include pages from the onlineencyclopedia, Wikipedia. The information stored for the inventory ofsuch pages may include a copy of the page, or it may include the URL ofthe page at the Wikipedia Web site.

In one embodiment, the inventory of pages may include advertisementsthat are reachable from other sources, or those that only exist for thepurpose of being linked to as described herein.

In one embodiment, each page in the inventory (the page or its URL) maybe stored associated with one or more tags. The tags may be the titlesof the web pages, anchor text from links in the web page, tags that weremanually assigned by the author of the web page or a different party, ortags that were automatically assigned, for example by identifying wordsor phrases not part of the HTML commands (e.g. “<strike>” or anchor textof a link) and repeatedly used on a page, words or phrases used in thetitles of web pages or both. Some or all of the tags correspond to thesubject matter of the page, the theme of the page, or other informationabout the page. In one embodiment, tags are stored as entities of a pageif the tag matches a tag in an index of potential tags. Each potentialtag in the index has a list of potentially matching terms.

From the inventory, the pages associated with tags that correspond toterms on the web page identified in step 310 are identified, anidentifier of the terms that correspond to that page are storedassociated with that page, and term scores for each such page areassigned, one for each term that corresponds to the page 318.

In one embodiment, only those terms for which a weighted combination ofterm search score, number of times the term was seen by the user score,interest indication score, and similar other user click score, exceeds athreshold are used to locate pages, and the other terms below thethreshold are ignored. The weights for each of these scores used tocompute the weighted combination may be identified using conventionalregression analysis techniques to maximize the number of times a userclicks at least one term on each retrieved page.

A tag may correspond to a term if it is the same as, or similar to, theterm. In one embodiment, a tag is similar to a term if the tag has oneor more words in common with the term, or one or more words in the tagare synonyms with one or more words in the term. A tag may correspond toa term if the term is on the index of potential tags as a term thatcorresponds to that tag.

A term score may be assigned for each term that corresponds to tags onthe page as part of step 318. The term score for the page may beidentified as a function of how closely any tag for the page matches theterm on the page retrieved in step 310, with identical words in both thetags and the term having a higher initial score than those that aresynonyms, and pages with higher percentage of the words in the tags forthe page being the same or similar to the term having a higher initialterm score than the term score corresponding to a term having words thatmatch few or none of the tags on that page. If the index is used, thescore for each potential term may be associated with each potential termfor the tag and the score for a page having a tag that corresponds to aterm may be identified by locating the score for the term that was usedto match the tag from among the scores assigned to terms matching thetag that matched the term. If multiple tags matched a term, the highestone may be used or an average may be used.

In the descriptions of matching terms to tags and scoring them, it isnoted that instead of matching terms to tags, tags may be matched toterms.

In one embodiment, a dictionary of words may be provided that lists thewords that can be used for purpose of analysis as described herein, andonly such words from a page being analyzed, the pages in the inventoryor both, are used for any purpose described herein.

Thus, for each inventory page, for each term to which that inventorypage corresponds, there is a term score assigned. Each combination ofterm and inventory page may have a different score, though some may endup with the same score.

D. Identify Scores for Pages.

1. Scores Relevant to the Context of the Term and 5 Trustworthiness.

For some or all of each inventory page identified in step 318, scorescorresponding to the quality of the page, and scores corresponding tohow desirable the user will find the page or how desirable the user willfind the page at the time, are identified as will now be described.

In one embodiment, a preference score is identified, a contextualrelevance score is identified and a trustworthiness score is identified320, for each page identified in step 318.

As noted below, the preference score may be identified either before orafter step 322 and if the preference score is identified before step322, in one embodiment, it is identified as part of step 320. In oneembodiment, each preference the user may select is associated with alist of a certain number (e.g. 100 or 1000) of words or sets of wordsthat web pages appealing to a person with that preference might contain.The preference score for the page is a function of the number of suchwords for any preference the user selected being on, or in the metadataof, the page, and the location of the word relative to the page (e.g.words in metadata or titles resulting in a higher score than the sameword as regular text in the body of the page). For example, a list ofsporting teams, names of players, coaches and owners, venues, sports andequipment may be associated with a “sports” preference, causing pagesthat have one or more of these words to have a higher preference scorethan pages that do not have any of these words. The type (as describedabove) of the web site containing the page may be used instead of, or inaddition to, words on the page, with each preference being associatedwith one or more types. If the user indicates the degree of eachpreference, the score may be a function of the degree corresponding tothe words matching on the page.

As noted above, step 320 includes identifying a contextual relevancescore for each term corresponding to the selected page. The contextualrelevance score is higher if the term as used in the selected inventorypage corresponds to the meaning of the term as indicated by the contextof the term relative to other words nearby the term on the pageretrieved in step 310 than it does if the term as used in the selectedinventory page does not correspond to the meaning of the term asindicated by the context of the term relative to other words nearby theterm on the page retrieved in step 310, i.e. the one corresponding tothe URL uploaded. For example, the term “nutty” may have a differentmeaning in the context of the actor Jerry Lewis than it would in thecontext of a peanut butter taste test. The contextual relevance scoremay be identified from the number of words nearby the term on theinventory page being analyzed that have the same or similar words in theselected page. A synonym table may be used to identify similar words.For example, if the term nutty came from the page being analyzed in thesentence, “Brand X peanut butter has a nutty flavor”, if the selectedinventory page uses the term “peanut butter” several times throughoutthe page, the selected inventory page will have a higher contextualrelevance score than if the term ‘nutty’ came from the sentence “JerryLewis starred in the Nutty Professor” because the selected web page mayuse the words “Peanut Butter” more than it uses “Jerry Lewis” or“Professor”. Other conventional methods of word sense disambiguation maybe used.

The contextual relevance score for a term may be multiplied by a weightand the product added to the term score for that term for the selectedpage. The weight may be determined via conventional regression analysisto optimize for one or more conditions, such as to attempt to increasethe clickback scores for the page when linked from the termcorresponding to the score.

In one embodiment, a trustworthiness score is identified as part of step320. The trustworthiness score is a function of how trust worthy thesource of the page is. In one embodiment, trustworthiness may bemeasured by the second level domain name (i.e. the domain of the website containing the inventory page being scored), the number of links topages in that domain and the quality of those links. A link has a higherquality if it comes from a domain on a list of trusted domains, or if itcomes from indirectly, that is, from a site from which a link to atrusted domain exists, via one or more other sites, with the qualitybeing lower with increasing levels of indirection.

2. Select First Contextually Relevant, Trustworthy Page, OptionallyMatching any User Preferences.

The first of the pages having a tag that corresponded to at least one ofthe terms and that has a combined preference score, trustworthinessscore and optionally, contextual relevance score, that exceeds athreshold is selected 322. The other inventory pages that do not havesuch a threshold combined score are not considered for the retrievedpage in one embodiment. The combined score may be produced by weightingeach of the component scores by multiplying each of them by its ownweight and summing the weighted scores. The weights may be identifiedusing conventional regression analysis techniques to attempt to producea combined score for each page that, when the combined score exceeds athreshold, the percentage of time the web page is clicked on by the useras described below is maximized and the number of times the user clicksback from the web page within a threshold amount of time of beingclicked on is minimized.

Other ways of filtering pages to select may be used, for example byselecting pages that have a threshold contextual relevance score,optional preference score, or a threshold trustworthiness score, forexample. In another embodiment, no threshold need be used and all pageshaving tags that correspond to terms are selected, one at a time.

3. Identify Score Based on Relevance of Each Page to the User'sPreferences,

In the embodiment in which the preference score is identified after step322, the preference score may be identified at step 324. In suchembodiment, one or more scores are identified based on the relevance ofthe page to the user's preferences. One such score is a preference scoreand such score is identified 324 for the selected page.

In one embodiment, each preference the user may select is associatedwith a list of 1000 or more words or sets of words that web pagesappealing to a person with that preference might contain. The preferencescore for the selected page is a function of the number of such wordsfor any preference the user selected being on, or in the metadata of,the page, and the location of the word relative to the page (e.g. wordsin metadata or titles resulting in a higher score than the same word asregular text in the body of the page). For example, a list of sportingteams, names of players, coaches and owners, venues, sports andequipment may be associated with a “sports” preference, causing pagesthat have one or more of these words to have a higher preference scorethan pages that do not have any of these words. The type (as describedabove) of the web site containing the page may be used instead of, or inaddition to, words on the page, with each preference being associatedwith one or more types. If the user indicates the degree of eachpreference, the score may be a function of the degree corresponding tothe words matching on the page.

4. Score Based on Actions of the User.

One or more scores based on actions the user has previously taken withrespect to the selected page is identified. One such score is a scorecorresponding to the average amount of time between the time the userpreviously clicked a link to the selected page, thereby causing the userto view the page corresponding to the link corresponding to the term,and then clicked back to the page on which the term was indicated asbeing a portal or link to additional information, and such a score isidentified 326. This same user click back score is lower if the averagetime difference between such events is low and higher if the averagetime difference is high. In one embodiment, if a user clicks back aftera threshold amount of time, the threshold amount of time (e.g. 5seconds) may be used when calculating the average in one embodiment. Inone embodiment, if the user does not click back, the average will not beaffected and in another embodiment, when a user does not click back, theuser is considered to have clicked back after a long amount of time,such as an hour. Other amounts may be assigned if the user does notclick back, as little as five seconds.

5. Scores Based on Similarity of Experiences of the User.

One or more scores is identified based on similarity of experiences ofthe user and how recent those experiences are.

One such score is a score corresponding to how similar the selected pageis to pages the user recently visited, and such score is identified 328.In one embodiment, the measure of how similar one page is to another ismade via a comparison of the same or similar words on the two pages,though other metrics of similarity may be used. The score is higher ifthe selected page has many words in common with the user's recentlyvisited pages and lower if it does not. Words that match or are synonymsmay be identified as being in common (e.g. using a conventionalthesaurus), with synonyms contributing less to the score than matches.Words in common that are contained in titles or metadata (e.g. pagetitle or description) may be given a higher weight in scoring than wordsin body text in common. In one embodiment, if the exact same selectedpage was very recently visited, however, the score may be at or nearzero or negative. In such embodiment, a page that is similar to pagesthe user visits are considered good candidates to which to link, but thesame page the user visited very recently are not considered goodcandidates to which the link.

In one embodiment, the contribution to the score from each page the uservisited is higher if the user had a higher level of engagement on suchpage (e.g. the user typing on the page or using a form element orfilling in a web form is higher than scrolling up or down, which ishigher than moving the mouse, which is higher than not taking any actionon the page) than if the user had a lower level of engagement with suchpage, and the more similar pages the higher the score.

In one embodiment, the database described above that categorizes websites according to a user's interests may be used to identify similarweb pages, for example identifying web sites as financial web sites, andother web sites as news web sites. The score may be higher if thecategories of the one or more web sites corresponding to pages in theuser's history are the same as the selected page than it is if thecategories of the one or more web sites corresponding to pages in theuser's history are the not the same as the selected page, with the scorebeing a function of the number of such web sites containing web pages inthe user's history that have the same category as the selected page.Pages that are more recent in the user's history may have a greatereffect on the score than pages less recent in the user's history. Theuser's history includes URLs uploaded as the user's history as part ofstep 216 as well as the individual URLs uploaded for analysis as part ofstep 220, each of FIG. 2 described above.

In one embodiment, pages that are viewed for less than a thresholdamount of time before the user clicks back from them are not consideredto be pages viewed by the user when identifying the score describedabove.

Another such score is a score corresponding to how relevant the selectedpage is, relative to recent searches of the user, and such score isidentified as part of step 328. The score may be higher if the selectedpage has many of the search terms of any recent search and lower if ithas fewer or no terms of any recent search. The contribution of a pageto the score may be higher if the recent search terms are in headerfields or title fields or other metadata fields of that page than if thesearch terms are in non header body text of the page. Terms from recentsearches may be weighted higher in the score than older searches.

6. Scores Based on Qualities of Each Page.

One or more scores based on other qualities of the selected page areidentified 330. One such score is an information type score.

In one embodiment, the information type score has different values forpages representing different information types. To identify theinformation type score, the type of the information is retrieved and thescore is assigned a value corresponding to the type of informationrepresented by the page.

An information type score may be used to provide a preference amongcertain information types for each page. For example, an advertisementor product page that might not have a large total score as describedbelow may have its total score increased via its information type score.Information types may be segregated into those that produce revenue forthe party performing at least a part of the system and method of thepresent invention and those that do not, and may be assigned by theentity that operates the server. Other types of information may beassigned than just the two types described above. If an information typefor a page is not assigned or unknown, it may be assumed to be a defaultvalue, such as “non revenue producing”.

The values for the information type score assigned to the types of webpages may be adjusted hourly to keep the number of revenue producingpages (or a different set of one or more information types) to whichlinks are built as described herein within an upper and lower boundpercentage of all pages to which links are built as described herein.Other types of pages may be constrained in the same manner based ontheir type or source. For example, pages from the web site wikipedia.commay be constrained to make up a percentage of web pages not higher thana certain percentage of the web pages to which links are made asdescribed herein by assigning all such pages their own information type.Each hour, the number of links built to each type of page or source maybe checked and the information type score adjusted in order to cause thepercentage to more closely approximate the center of the range definedby the upper and lower bounds for that type or those types. In thiscase, a list of web sites or URLs and their types may be used byassuming all pages correspond to the type of the site hosting the pageunless a different type is assigned to the URL of the page, with URLs orweb sites not on the list assumed to have a default type.

In one embodiment, subtypes may be assigned within types and eachinventory page is assigned to a type and subtype that represents thecontent of the page. Categories may be “movies”, “people”, “places”, and“other”, for example, though still other types may be used. Differentvalues described above may be assigned based not only on the type, butalso the subtype to which the page was assigned.

7. Score Based on Prior Actions of Other Users.

One or more scores is identified based on prior actions of other users.One such score is a similar other user click back score and such scoreis identified 332. The similar other user click back score is higher ifother similar users (as described above) did not rapidly click back fromthe selected page when they click on a link to that page when it islinked from the same term and lower if such users rapidly click back,each on a percentage basis. In one embodiment, if the other similar userdoes not click back, the average will not be affected and in anotherembodiment, when another similar user does not click back, the othersimilar user is considered to have clicked back after a long amount oftime, such as an hour. Other default periods, such as five minutes orfive seconds, may be assigned.

Another score is a similar other user level of engagement score for theinventory page. The similar other user level of engagement score ishigher if the other user had a higher level of engagement on such page(in the same manner as described above) than if the user had a lowerlevel of engagement with such page, and the more such other users, thehigher the score.

The scores described above utilize the information uploaded not only bythe user's client computer system, but also that uploaded by otheruser's client computer systems. When the server receives suchinformation, it is stored with the date and time of receipt and the useridentifier. For example, click back times can be identified by analyzingthe time page A was loaded, then page B that corresponded to a linkprovided, and then page A was reloaded: the click back time is the timedifference between the second time page A was loaded and the time page Bwas loaded.

In one embodiment, the two types of click back scores described abovemay be affected by other actions such as scrolls up or down, page up ordown, etc. that the user performed after clicking to the pagecorresponding to a link provided by the server.

Thus, in one embodiment, the scores assigned to each inventory page area preference score, a contextual relevance score, a trustworthinessscore, one or more scores based on actions the user has previously takenwith respect to the selected page, one or more scores identified basedon similarity of experiences of the user and how recent thoseexperiences are, one or more scores based on other qualities of theselected page, one or more scores identified based on prior actions ofother users.

8. Assign Page Score, Store all Scores, Select Next Page.

The scores described above in steps 324-332 are multiplied by weightsfor each of those scores and the results summed and assigned to the pageas the page score. The weights may be set and adjusted to minimize clickbacks within a threshold amount of time, maximize revenue, or both ofthese, initially using conventional regression analysis or other similartechniques, and then adjusting the weights to attempt to optimize clickback times, revenue or both.

In another embodiment, step 324 is performed before step 322 and the oneor more scores identified in step 324 are used to select the pages instep 322 weighting and combining such score or scores in the same mannerdescribed above. In such embodiment, the one or more scores described insteps 324 may or may not be used as described above in the precedingparagraph. However, in another embodiment, any or all of the scores insteps 324 as well as step 320 (e.g. the trustworthiness score) may alsobe weighted and used with the other scores in the immediately precedingparagraph. Other forms of modeling may be used to produce the variousscores described herein, including linear or non linear models,supervised learning models or unsupervised learning models or othertypes of models.

The URL for the page and corresponding terms for which the page wasselected and, for each such term, the term score, are stored 340, and ifthere are more pages 342, the next page that corresponded to at leastone of the terms for which the weighted combination of term searchscore, number of times the term was seen by the user score, interestindication score, and similar other user click score, exceeds thethreshold as described above; and that has a combined preference scoreand trustworthiness score optionally combined with the contextualrelevance score, that exceeds a threshold is selected 344 in the samemanner as described above, and the method continues at step 318 usingthe newly selected page.

E. Score Pages for Each Term.

There may be a many-to-many relationship between terms being analyzed asdescribed herein and pages to which such terms may be linked. Thus, aninventory page may correspond to more than one term on the page beinganalyzed, and a term may have more than one inventory page to which itcorresponds. In one embodiment, to identify the terms that will beindicated as being portals or links to additional information, as wellas which inventory page (or pages) will be linked to that term, a totalterm score is computed for each term corresponding to each inventorypage that was selected as described above.

In one embodiment, each inventory page selected in steps 322 or 342 isassigned a total term score for each term score that page has. The totalterm score for a term and inventory page is a weighted combination ofthe term score for the term and inventory page assigned as described instep 318, all of the scores computed as described above in for thatterm, described in steps 312-316, and all of the scores for that page,computed as described above in steps 320 and 324-332. The weights may beidentified using conventional regression analysis techniques to minimizeclickbacks that are under a threshold, maximize revenue, maximize othergoals or maximize a function of multiple goals.

To review, a total term score is assigned to each term to which aninventory page corresponds. Thus, an inventory page that corresponds tothree terms, will have three total term scores. If a different inventorypage also corresponds to one of those three terms, that page will have atotal term score that corresponds to that term and page, and the totalterm score for the same term may have a different value for each page.The total term score is a function of how applicable the term isbelieved to be to the user and how applicable a page is believed to beto the user and the term. Other ways of deriving a similar score foreach combination of term and page may be used.

F. Select Pages with Highest Scores Subject to Other Constraints.

If there are no more pages 342, the page with the highest total termscore is selected (with ties broken by selecting the page with the termcorresponding to its highest score that is furthest from the other termsmarked for the page as described below) and the total term score iscompared to a threshold 346. If the total term score is above thethreshold 348, in the case of the first selected page the page isassigned to an instance of the term corresponding to that total termscore on the page 352. As a result of the assignments made herein, thepage will be linked from the term indicated as being a portal or link toadditional information so that the user can click on the term indicatedas being a portal or link to additional information and view the page.In the case of the first page assigned, the instance of the term may beselected at random. The page is marked as used and the term is marked ascompleted as part of step 352.

The page that has the highest total term score is selected from amongthe pages not marked as used for terms that are not marked as used andthe position of the instances of the terms on the page is checkedagainst the other instances marked as used for other pages to ensurethat an instance of the term corresponding to the highest total termscore selected is not near one of the other instances of a differentterm to which a page has been assigned 354. In one embodiment, if nosuch instance of the term is available, if the same page has a one ormore different terms with the same term score, any of those terms may beused to identify an acceptably located term instance may be identifiedto which the page may be assigned that is not too close to the otherterm instances marked, and if this is not possible, for the pagesalready assigned to terms as described herein, an attempt may be made toreassign such pages to different instances of the those terms (or toother terms with the same term score for each such page) in an attemptto spread out the instances of terms to which pages are assigned so thatthey are not too close together on the page retrieved in step 310 aspart of step 354. In one embodiment, terms nearer to the other terms byless than 5 percent of the number of words on a page are considered tobe too close together.

In one embodiment, the location of the words on the page is used tospread around the page the terms indicated as being a portal or link toadditional information. Thus, a term that is directly over another termthat has been assigned to be indicated as being a portal or link toadditional information on the page will be considered too close to theother term, even though there may be many words between them. In suchembodiment, a distance vector to the nearest other term on the page maybe identified and a minimum distance enforced. The minimum may be afunction of the various scores described herein, allowing a term with ahigher score to be indicated as being a portal or link to additionalinformation closer to another term indicated as being a portal or linkto additional information than it would be allowed to be if one or morescores were lower.

In the event that previously assigned terms are changed, marks andassignments are adjusted as needed to correspond to those terms andpages used.

Additionally as part of step 354, the number of marked terms is comparedto a maximum number of allowable marked terms on a page (e.g. 5) andother thresholds may be compared, for example, a maximum number of pageof a given type assigned to the page (e.g. no more than two revenueproducing pages assigned to any page). In one embodiment, the maximumnumber of pages of a given type may be identified as a function of theintent identified as described above. For example, the maximum number ofrevenue producing pages (e.g. advertisements) may be higher if theintent is “purchase” than if the intent is something other than“purchase”.

If the number of marked terms is equal to the maximum 356, the methodcontinues at step 358. Otherwise 356, if the total term score is notabove the threshold 348, the method continues at step 358.

If the total term score is above the threshold 348, if other thresholdsare not exceeded and an acceptably positioned instance of a term wasfound for the page corresponding to the identified score 350, the methodcontinues at step 352 and otherwise 350, the page is marked 360 and themethod continues at step 354.

In one embodiment, instead of scoring all of the inventory pages, thepages are scored as described above in descending order of contextualrelevance and those with the highest total term score above a total termscore threshold are marked until the maximum number of differentinventory pages have been so marked.

G. Update Databases of Terms Seen and Number of Times Indicated as beinga Portal or Link to Additional Information; Provide Term InstanceInformation and Related Information to Client.

At step 358 a database of terms each user has seen, the number of timesthat user has seen the term and the current date it was seen is updatedfor each term identified for the page retrieved in step 310, and adatabase of terms indicated as being a portal or link to additionalinformation each user has seen, the number of times that user has seenthe term indicated as being a portal or link to additional informationand the current date it was seen, is updated for each term marked asdescribed above. To update the database, the term, date and useridentifier are added to the database.

For each term, the term, the instance of the term to be indicated as aportal or link to additional information and URLs of inventory pagesassigned to the instance of the term as described above are provided tothe client as part of step 358 and the method continues at step 310. Asnoted, the terms and instances may be provided initially and the URL orURLs for each term may be provided by the server to the client uponrequest from the client when the client receives an interest indicationfor the term. Each term and instance and the URL may be stored by theserver associated with the user identifier to allow it to be providedupon request at the later time, by the client sending to the server theuser identifier and term.

In one embodiment, instead of, or in addition to indicating terms in apage as portals or links to additional information, a button or otheruser interface element may be displayed to the user (e.g. on the user'sbrowser) that, when clicked, allows the user to receive an inventorypage relevant to the page they are viewing. The user interface elementmay be displayed differently (e.g. using different colors) based on howrelevant the inventory page is to the user or to the page the user isviewing or to the user in general. The inventory page that is displayedif the button is clicked may be one of the inventory pages describedabove (e.g. the one with the highest overall total term score) or it maybe a different score computed for this purpose. For example, theinventory page displayed when the button is clicked may be the inventorypage that has the highest sum of all total term scores computed for thepage that exceed a threshold, i.e. summed across each term on the page.Thus, an inventory page that has a total term score that exceeds thethreshold for many, many terms on the page may be selected for displayover an inventory page that has at least one higher total term score,but corresponds to fewer terms on the page retrieved. The total termscores used for the selection of the inventory page displayed orotherwise provided to the user when the user clicks the button may beweighted differently than the total term score used as described above,in essence, employing two total term scores for each one describedabove, one used for the purpose of indication as a portal or link asdescribed above, and another used for the purpose of selecting theinventory page to be used to provide to the user when the user clicksthe button.

The delivery to the user of inventory pages may be made using links asdescribed herein, but also may be made via other sources, such as aspecific user interface element that is integrated into a browser ormade as a part of a separate application, or via e-mail or a mobilephone or tablet application that is linked to the user identifier usingconventional techniques (e.g. the user could provide an e-mail addressor mobile phone number or other identifier as part of the registrationprocess described above, or the user could receive their user identifieras part of the registration process or at a later time and enter it to amobile phone application that would register it to a server, which wouldmake the link between the two applications. In the case of inventorypages provided to the user, the inventory pages may be content otherthan web pages (e.g. they may be embedded into an e-mail or content thatwill be displayed by an application).

The inventory page that would be provided to the user if the userclicked the button may be the inventory page provided to the user, andin one embodiment, such pages are pushed to the user without the userclicking on any button. Just by visiting a web page, such inventory pageor pages may be provided to a user.

Multiple such inventory pages may be combined and provided to the userat the same time. Instead of choosing one inventory page to provide tothe user, those with the highest N scores described above may beprovided to the user.

Inventory pages may be provided to a user after the user visits severalpages. Thus, the scores for inventory pages may be cumulated acrossmultiple retrieved web pages and used to select the one or moreinventory page to be provided to the user.

System.

Referring now to FIG. 4, a system for adding information, such as linksto related information, to web pages is shown according to oneembodiment of the present invention. The system shown in FIG. 4 includesa client computer system 410 coupled to a server computer system 450 viaa conventional network 440 such as the Internet, an Ethernet network orboth. In one embodiment, the server computer system 450 is coupled tomultiple client computer systems 410 though other numbers of each may beused. Each of client computer system 410 and server computer system 450has a communication interface 416, 456, each of which includes aconventional TCP/IP-compatible communication interface running suitablecommunication protocols. All communication to and from client computersystem 410 is provided via client communication interface (which isadditionally coupled to a conventional keyboard/mouse/monitor not shown)416 and all communication to and from server is provided via servercommunication interface 456.

Browser 420 is a conventional browser, such as those described above. Inone embodiment, the user may use browser 420 to view web pages and todownload installation manager 422 which downloads and installs elements424, and 430-438 as an add on, extension, separate application, etc. asdescribed above.

Installation manager 422 signals client registration manager 424, whichrequests and receives from server registration manager 470 a uniqueclient identifier for the installation. Client registration manager 424stores the unique client identifier into registration storage 426 andprovides a user interface to the user to allow the user to providedemographic and/or interest and preference information about himself asdescribed above, and client registration manager 424 provides suchinformation to server registration manager 470 with the unique clientidentifier. Server registration manager 470 stores the information itreceives into user information storage 472 associated with the clientidentifier it receives. In one embodiment, instead of receiving andforwarding such information, client registration manager 424 directsbrowser 420 to a web page provided by server registration manager 470and includes URL parameter passing information (to the right of a slashthat is itself to the right of the address of the web page in the URL)which includes the client identifier. Server registration manager 470may prompt the user for and receive such information directly from theuser, and store it as described above. In one embodiment, serverregistration manager 470 adds a cookie with an encrypted version of theclient identifier to allow the client identifier to be obtained for useas described herein.

In one embodiment, installation manager 422 performs any functionsnecessary to receive notifications of the user's actions such as viewinga new web page, scrolling on a web page, hovering, clicking or typing ina browser window, and/or typing in, operating, or otherwise interactingwith a web form. Such functions may be inherent in the installationprocess or they may be explicitly performed, such as by registering toreceive such notifications from browser 420. As described herein, thesystem works to add functionality to a browser in one embodiment, butthe other arrangements described above may be used in other embodiments,and so actions described herein may be performed with respect toinformation other than web pages.

Page notification manager 430 receives from browser 420 a notificationthat the user has clicked on a new page (or has switched tabs onto anexisting page or changed the focus back to the browser from anotherapplication or the operating system) and receives from browser 420 theURL of the page. Page notification manager 430 provides the URL of thepage and the client identifier stored in registration storage 426 topage analysis manager 476 of server 450.

When it receives the URL, page analysis manager 476, which is describedin more detail with respect to FIG. 5, below, analyzes the page asdescribed herein, and returns to page notification manager 430 theinstances of the terms that should be indicated as being a portal orlink to additional information as described herein. Page analysismanager 476 stores the date and time of receipt of the URL, the URL, theterms and the additional information into user information storage 472associated with the client identifier it received.

User information storage 472, registration storage 426, and adminstorage 462 may include conventional memory or disk storage and mayinclude a conventional database.

When it receives the terms and instance information, 20 pagenotification manager 430 instruments the web page to so indicate suchinstances of such terms as described above and to receive an indicationof the term if the user hovers over a term on the page for more than athreshold amount of time as described above.

If the user hovers over one of the indicated terms, browser 410 willindicate the term and the URL of the web page to interest indicationmanager 432. In response, interest indication manager 432 will send theURL and a reference of the term over which the user hovered and theclient identifier stored in registration storage 426 to additionalinformation manager 478, which stores into user information storage 472the term over which the user hovered, the client identifier and the dateand time of receipt (obtained from an operating system, not shown) anduses the client identifier, URL and an identifier of the term to locatethe additional information for that term using the most recent set ofinformation for the URL and client identifier received and provides theadditional information to interest indication manager 432. Interestindication manager 432 displays the additional information as describedabove as part of, or separately from, the information being displayed bythe browser, and the browser may retrieve pages corresponding to anylinks the user presses. The area around the link may be instrumented byinterest indication manager 432 to cause browser 420 to indicate thatthe user has clicked the link to click manager 436. If the user clicksthe link, click manager 436 sends the term, URL of the link clicked andthe client identifier in registration storage 426 to action manager 474,which adds the date and time of receipt and stores all such informationinto user information storage 472.

In the event the user clicks back from a page, browser 420 will soindicate to click back manager 438. Such operation may be arranged aspart of the installation process arranged by installation manager 422.If such an indication is received, click back manager 438 provides theclient identifier from registration storage 426 and an indication thatthe user has clicked back to action manager 474 which stores into userinformation storage 472 the indication and client identifier and thedate and time of receipt it retrieves from an operating system (notshown). In one embodiment, browser 420 provides click back manager 438the URL of the page from which the user clicked back and click backmanager 438 provides the URL to action manager 474, which stores it withthe other information described above.

In the event that the user scrolls up or down, moves the mouse around,interacts with, or types into, the page or a form on the page orperforms another action that indicates the user is reviewing orinteracting with the page or a form on the page as described herein,browser 420 informs review/interaction manager 434 of the actionperformed. Such operation may be arranged by installation manager 422 aspart of the installation.

Review/interaction manager 434 provides the client identifier fromregistration storage 426 and the indication of the action to actionmanager 474, which stores into user information storage 472 the clientidentifier, an indication of the action or type of action (e.g. the userappears to be reviewing the page due to a scroll, page up or down ormoving the mouse, in which case the type is a “review”, or the userappears to be actively engaged with the page by typing or interactingwith a form element on the page, in which case the type is “engage”) andthe date and time of receipt retrieved from an operating system (notshown). In one embodiment, review/interaction manager 434 only sendsindications once every few seconds. If two of the same indications orsame type of indications are received in rapid succession and then noneare received, review/interaction manager 434 may only send one of them,in order to indicate to action manager 474 that the user was engagedwith the page, without sending every indication.

Referring now to FIGS. 4 and 5, page analysis manager 476 of FIG. 4 isshown in FIG. 5 in more detail according to one embodiment of thepresent invention. Page receipt/intent manager 508 receives viainput/output 558 the client identifier of the user and the URL of thepage, and stores them and the date and time of receipt it retrieves froman operating system into a page object. Page receipt/intent manager 508stores the information received and the date and time of receipt intouser information storage 472 as described above.

Page receipt/intent manager 508 identifies the intent of the user asdescribed above and stores the intent into the page object. In oneembodiment, page receipt/intent manager 508 identifies the intent basedon the second level domain in the URL received and a database of secondlevel domains and their corresponding intents that an administrator hasstored into administration storage 462 using a user interface providedby administration manager 464. When page receipt/intent manager hasfinished identifying the intent, page receipt/intent manager 508provides the page object to page retriever 510.

When it receives the page object, page retriever 510 retrieves from theInternet or a cache the Web page specified by the URL of the page objectand stores the contents of the page into page storage 512 and adds theURL, date and time of retrieval, and the expiration date and time fromthe expires header to an index of pages stored in page storage 512. Inone embodiment, page retriever 510 first checks the index and expirationdate and time to determine if the page is expired by comparing theexpiration date and time with the current date and time it retrievesfrom an operating system, and only retrieves the page if it is not inthe cache and not expired. Page retriever 510 associates in userinformation storage 472 the page in page storage 512 with the clientidentifier in the page object. Page retriever 510 adds a pointer to thepage in page storage 512 to the page object and provides the page objectto term seen manager 514.

When it receives the page object, term seen manager 514 identifies theterms on the page as described above and stores the terms into userinformation storage 472, associated with the date and time and clientidentifier from the page object. Terms seen manager 514 stores the termsinto the page object. In one embodiment, multiple instances of the sameterm are treated as separate terms and are stored separately in the pageobject. In this embodiment, an indication of where the term was locatedon the page is stored associated with the term in the page object byterms seen manager.

For each term, identifies the score corresponding to the number of timesa user corresponding to that client 5 identifier has seen that term asdescribed above, and stores the number of times the term was seen by theuser score, for each term into the page object associated with the termto which the score corresponds. To compute such score, for each term inthe page object, terms seen manager 514 identifies in user informationstorage 472 the number of times the user has seen the term andoptionally the date and time the user saw the term and computes a termscore as described above.

Terms seen manager 514 provides the page object to 15 term searchrelevance manager 516.

When it receives the page object, term search relevance manager 516computes the term search relevance score for each term in the pageobject using the search terms received from and stored for that user inuser information storage 472 as described herein, stores the term searchrelevance score for each term into the page object associated with thatterm, and provides the page object to term indicated manager 518.

When it receives the page object, for each term therein, term indicatedmanager 518 identifies, for each term in the page object, the scorecorresponding to the number of times the term was indicated as being aportal or 5 link to additional information as described above, using theinformation in user information storage 472 about terms indicated to theuser corresponding to the client identifier in the page object, andstores into the page object each such score associated with itscorresponding 10 term. Term indicated manager 518 provides the pageobject to similar other user click manager 520.

When it receives the page object, similar other user click manager 520uses the information about the user and other users stored in userinformation storage 472 as described herein to identify similar otherusers as described above and identifies, for each term in the pageobject, the score corresponding to similar other users clicking linksfrom that term as described above and stores the score for each term inthe page object associated with that term. Similar other user clickmanager 520 provides the page object to page identification manager 522.

When it receives the page object, pages identification manager 522identifies, as described above, the inventory pages corresponding to theterms in the page object, and stores, for each such inventory page, anidentifier of the pages, such as the URLs of such pages, associated witheach term to which such inventory page corresponds.

In one embodiment, inventory pages are periodically retrieved into pagestorage 512 by page retriever 510 using a list of URLs of pages toperiodically retrieve that a system administrator may administer using auser interface provided by page retriever 510, which receives them. Pageretriever 510 stores the list into page storage 512 and uses the list toretrieve the pages. In one embodiment, a second level domain name may beprovided for each of several domains, in which case page retriever 510spiders the domain and retrieves all pages it can locate. In oneembodiment, page retriever 510 tags pages it retrieves from the list asdescribed above and stores the tags associated with the URL. A human maycheck the tags or manually add or change a tag in page storage 512 usinga system administration computer system (not shown) coupled to theInternet and a user interface provided by page retriever 510.

Pages identification manager 522 identifies the term score for each suchpage as described above and stores the term score into the page object,associated with the term and page identifier. Thus, the term score inthe page object identifies, for each term corresponding to an inventorypage, how well the inventory page corresponds to the term.

In one embodiment, if the term appears more than once on the page, aterm score is assigned to each instance of the term, for example in theorder in which the term appears in the terms stored in the page object.

When it has completed identifying inventory pages and assigning termscores, pages identification manager 522 provides the page object tocontextual relevance manager 524.

When it receives the page object, contextual relevance manager 524identifies, as described above, the contextual relevance score for eachinventory page using the term to which the inventory page corresponds,the page being analyzed stored in page storage 512, and the inventorypage stored in page storage 512, and then weights and combines asdescribed above the contextual relevance score into each term score inthe page object corresponding to the term for each inventory page forwhich the contextual relevance score corresponds. Contextual relevancemanager 524 provides the page object to user preference manager 532 inthe embodiment in which the preference score is used to select pages asdescribed above, or to trustworthiness manager 528 otherwise.

When it receives the page object, user preference manager 530 identifiesand stores in the page object for each inventory page identified in thepage object, a preference score as described above, using the preferenceinformation stored in user information storage 472 corresponding to theclient identifier in the page object, the text of the inventory pagestored in page storage 512 and other information such as a list of wordsthat a system administrator may store into administration storage 462via a user interface provided by administration manager 464.Administration storage 462, user information storage 472 and pagestorage 512 may include conventional memory or disk storage and mayinclude a conventional database. When it has completed storing thepreference scores preference manager 530 provides the page object totrustworthiness manager 528 in the embodiment in which the preferencescore is used to select pages by page selection manager 530 and to sameuser click back manager 532 otherwise.

When it receives the page object, trustworthiness manager 528 computes,as described above, the trustworthiness score for each inventory pagespecified by the page object and stores the trustworthiness scoreassociated with the inventory page into the object. Lists of initialtrustworthy web sites may be stored by a system administrator intoadministration storage 462 via a user interface provided byadministration manager 464, and trustworthiness manager 528 mayperiodically spider the web from such sites using conventionaltechniques to identify the trustworthiness score of a page by decreasingthe trustworthiness score for a site the larger number of hops acrossdifferent links it takes to reach the site from the initial trustworthysites, and increasing the trustworthiness score of a page the more linksthere are to the site or to the page. Trustworthiness manager 528 maystore such trustworthiness scores into administration storage 462, alongwith the date and time, and the most recent trustworthiness score isused. The trustworthiness score of sites on the initial trustworthysites list may be higher than other sites, and pages from those siteshave the highest trustworthiness scores. When it has completedidentifying the trustworthiness of each such inventory page,trustworthiness manager 528 provides the page object to page selectionmanager 530.

When it receives the page object, page selection manager 530 selects theinventory pages selected as described above using any or all of thecontextual relevance score, trustworthiness score and preference score,and the scores assigned to the terms as described herein and indicatesthe selected inventory pages in the page object. As opposed to the oneat a time processing of the selected pages described above, as describedherein, the selected pages may be processed in a batch of all inventorypages by the various elements described below, and each technique (oneat a time processing or batch processing) may be used in the method,system or computer program product.

In the embodiment in which the preference score is not used to selectthe inventory pages by page selection manager 530, page selectionmanager provides the page object to user preference manager 532, whichidentifies a preference score for each of the selected inventory pages,stores the preference score for each inventory page in the page objectassociated with the identifier of the inventory page (e.g. the URL) andprovides the page object to same user click back manager 534. Thepreference score may be identified from the preferences of the usercorresponding to the client identifier in the page object, suchpreferences being stored in user information storage 472, the list ofwords stored in administration storage 462 via a user interface providedby administration manager 464, and the contents of the inventory pagesstored in page storage 512. In the embodiment in which page selectionmanager 528 uses the preference score to select the inventory pages,page selection manager 530 provides the page object to same user clickback manager 534.

When it receives the page object, same user click back manager 534computes as described above the same user click back score for each ofthe selected pages, stores the same user click back score for each suchpage into the page object associated with the identifier of theinventory page to which it corresponds and provides the page object topages visited manager 536. Click backs for the user may be identified bythe user clicking on a web page via a link inserted as described herein,and then clicking back within a threshold amount of time, as recorded inuser information storage 472 for the user having the client identifierin the page object.

When it receives the page object, pages visited manager 536 computes, asdescribed above, the score corresponding to how similar the selectedpage is to pages the user recently visited for each selected page (asdescribed above), stores such score (the “similar to pages visitedscore”) into the page object associated with the identifier of theinventory page to which such score corresponds and provides the pageobject to search terms used manager 538. To identify the score, the textfrom pages the user visited stored in page storage 512 and associated inclient information storage 472 with the client identifier in the pageobject, or those visited without clicking back for at least a thresholdamount of time, are used as described above. The actions the userperformed while on the page (e.g. those that indicate the level ofengagement) may be used as described above. The text from the pages maybe stored in page storage 512, and a reference to the page and clientidentifier, along with the date and time may be stored by page retriever512 into user information storage 472 when it retrieves the page asdescribed above.

When it receives the page object, search terms used manager 538identifies the score indicating how relevant each selected page is,relative to recent searches of the user as described above. In oneembodiment, when a URL for a web page from conventional search enginesis received with the search terms used, instead of retrieving andstoring the page, page retriever 510 stores the search terms associatedwith the client identifier and the date and time into user informationstorage 472 and search terms used manager 538 uses such search terms asdescribed above and the contents of each inventory page stored in pagestorage 512. Such score is stored by search terms used manager 538 andstored into the page object associated with the selected page to whichsuch score corresponds, for each selected inventory page. Search termsused manager 538 provides the page object to information type manager540.

When it receives the page object, information type manager 540identifies the score based on the information type of each selectedinventory page in the page object using a list of inventory page typesfor each URL or domain name that a system administrator stores intoadministration storage 462 using a user interface provided byadministration manager 464, and the URL or domain name within the URL ofeach selected inventory page in the page object. Information typemanager 540 stores each such information type score into the page objectassociated with the inventory page to which it corresponds and providesthe page object to other user score manager 542.

When it receives the page object, other user score manager 542identifies, for each selected inventory page specified by the pageobject, the similar other user click back score and similar other userlevel of engagement score for such page as described above and storessuch scores into the page object associated with the inventory page towhich each such score corresponds. To identify such scores, other userscore manager 542 identifies similar other users using the preferenceinformation stored into user information storage 472 or using the URL ofthe web pages the user corresponding to the client identifier in thepage object has viewed and the URL of the web pages such other usershave viewed, stored in user information storage 472; preferences of suchuser and other users stored in user information storage 472 or both, andthe actions such users performed on each page, or indications thereof,to identify the level of engagement as described above. For eachselected inventory page in the page object, other user score manager 542assigns a similar other user click back score based on whether theinformation in user information storage 472 indicates the user clickedon any such pages and either clicked back quickly or did not click backquickly, as described above. Other user score manager 542 stores in thepage object the similar other user click back scores and the similarother user level of engagement score to each selected inventory pageassociated with the identifier of the selected inventory page to whichthe similar other user click back score corresponds. When it hascompleted identifying the similar other user click back scores andsimilar other user level of engagement scores, other user score manager542 provides the page object to scores assignment manager 544.

When it receives the page object, scores assignment manager 544 computesas described above, for each selected inventory page specified by thepage object, the total term score for each term corresponding to eachsuch inventory page specified by the page object and stores into thepage object the total term score for each term corresponding to eachpage, associated with the page identifier and the term. When scoresassignment manager 544 has finished computing and storing the total termscores for each selected page and each term corresponding to that page,scores assignment manager 544 provides the page object to high scoreselection manager 546.

When it receives the page object, high score selection manager 546identifies the highest total term scores corresponding to N terms thatare different from another, and indicates in the page object the highesttotal term score for each of the N terms, by indicating in the pageobject, the inventory page and the instance of the term with suchhighest score. Thus, if N is 3, and two instances of the same term havethe highest and second highest total term scores, only the instance ofthe term (and the inventory page to which it corresponds) with thehigher of the two total term scores will be indicated from among thosetwo term scores, so that the N terms indicated will not have anyduplicate terms that are merely different instances. High scoreselection manager 546 marks the term on the page object for which eachinventory page is being indicated, and provides the page object tothreshold check manager 548, which checks to make sure the indicatedtotal term scores meet the minimum threshold described above, andoptionally that no more than a maximum number of types of inventorypages are indicated. Page types used by threshold check manager 548 maybe stored by a system administrator associated with the page contents inpage storage 512. If any total term score does not exceed the minimumthreshold for a total term score, the indication for that total termscore is removed by threshold check manager 548, and thus in thatcircumstance, the page will have fewer than N terms that will bedisplayed as portals or links to additional information. In the eventthat a 5 page type has exceeded its threshold, threshold check manager548 will mark in the page object as invalid, one or more indicationswith the lowest total term score corresponding to inventory pages thatexceed the threshold number for their type as described above, and willreturn the page object to high score selection manager 546 along withthe type of inventory pages whose thresholds were exceeded and thenumber of pages whose indications were removed. High score selectionmanager 546 will select that many total term scores corresponding toother pages from the next highest total term scores (e.g. the ones withscores immediately below the lowest one previously indicated) for termsthat are different from one another and different from each other, andare not the same type received, indicate the inventory pagescorresponding to the selected total term scores, and provide the pageobject to threshold check manager 548, which repeats the process ofchecking. Threshold check manager 548 will either return the page objectto high score selection manager 546 with the other information describedabove if thresholds are exceeded or, if none of the thresholds areexceeded, will provide the page object to position manager 550.

In one embodiment, page notification manager 430 retrieves or receivesfrom browser 420 the dimensions of the window in which the page havingthe URL it provides is displayed. Page notification manager 430 providessuch dimensions with the other information it provides to page analysismanager 476. Page receipt/intent manager 508 adds such dimensions to thepage object with the other information as described above.

When it receives the page object, position manager 550 checks theposition of the terms indicated using the dimensions of the window inthe page object (or default dimensions may be assumed) and the contentsof the page in page storage 512 as described above. If the positions ofthe terms indicated are sufficiently dispersed on the page as describedabove, position manager 550 provides the page object to response manager554 and otherwise position manager 550 marks the indicated terms thatare too close to one another in the page object and provides the pageobject to position reassignment manager 552.

When position reassignment manager 552 receives the page object,position reassignment manager 552 reassigns the indicated terms so thatthey are not too close to one another as described above, removingindications in the page object from terms formerly indicated that itreassigns and adding indications in the page object for the terms itnewly assigns as described above, and provides the page object toresponse manager 554.

When response manager 554 receives the page object, response manager 554provides the indication of the instance of the N terms indicated at theinput/output 558 to the client computer system 410 as described above.In one embodiment, a serial number unique to the client identifier isalso provided with such response.

In one embodiment, the URL received, the client identifier, the uniqueserial number, and identifiers of the URLs for the pages assigned to theN indicated terms from the page object, as well as other informationfrom the page object, are stored into user information storage 472 byresponse manager 554 for use as described herein, for example, toprovide the additional information.

In one embodiment, the identifiers of the pages for each term are storedin user information storage 472 in the same order as the terms wereprovided. To obtain the additional information for a term, interestindication manager 432 provides the client identifier, the unique serialnumber, and an index of the term to allow additional information manager478 to retrieve the identifier of the inventory page from userinformation storage 472. Additional information manager 478 may then usethe identifier of the page to retrieve any additional information frompage storage 512 that is not already stored in user information storage472 and provides the additional information in response as describedherein.

Thus, links from a web page that were not supplied by the author of theweb page are enabled for use by a user from any web page a user views,and the web pages reached by such links are custom tailored to be thoseof most interest to the user, even though they are not linked by theauthor and not necessarily on the same web site as the web page the useris viewing. The enabling of such links is performed by an entityindependent from the entity that operates the web page being viewed, andmay be independent of the entities that operate each web site containingthe pages to which the page being viewed will be linked.
